6. Sam & Cat Was A Smash Hit
After 3 seasons on screen, Victorious was canceled, but Ariana’s time on TV was not over. Nickelodeon commissioned a spin-off series Sam & Cat with her and Jennette McCurdy. It too would be canceled and only spent a single season on TV, but the channel doubled the number of episodes from 20 to 40 because the show was hugely popular during its airing.
